"We didn't really scrutinise the receipt so we just paid," said Kay.Īs the lunch was a treat for the two departing colleagues, the bill was split among the other six. Group only realises dish cost S$72 afterwards Still, she recalls that the dish "tasted good", and was up to their expectations. When the dish arrived, the group realised that it was not regular dou miao - which tends to have smaller shoots and leaves compared to what they had been served. The group agreed to the waitress' suggestion without asking the price. They chose Teochew seafood mee sua for the noodle dish, and wanted to order a vegetable dish as well.Īccording to Kay, their waitress chimed in to recommend the dou miao, which was not listed on the menu.Īs Kay recalls: "She suggested and said something like 'today we have a dou miao dish, would you like to try it?'" The group decided to order dim sum, and decided to add on some items from the à la carte menu. Kay shared that it was her first time at the restaurant, Paradise Teochew at Takashimaya, on Nov. The S$72 dish of 蒜蓉炒豆苗(大) (dou miao fried with minced garlic (large)). One of the diners, Kay (not her real name), shared her experience with Mothership. The dish in question was a plate of vegetables, indicated on the receipt as "蒜蓉炒豆苗(大)" (Or, "dou miao fried with minced garlic (large)"). What shocked them, however, was the S$72 price tag for one of the dishes. : Updated based on feedback from Dan Wing.They ordered dim sum for a table of eight diners and paid a total of S$533.16 for the meal. Johannes Weber described the challenges of using VPNs with dynamic IPv6 prefixes in his Troopers 2018 presentation… and it’s not a pretty picture.Īnything else I’ve missed? Please write a comment. You could solve 95% of this problem with host-based IPsec VPN or SSL VPN (in both cases you don’t care about the transport IP address of the client) or with SSL proxy, but there’s always the problem of remote printers and IP phones. Lots of SOHO offices or remote workers do – one the uplinks is a site-to-site VPN with the mothership. You might wonder how many small sites really need two uplinks. IETF has been tackling various aspects of this elephant for a decade and still hasn’t got anywhere close to solving it. They won’t pay for enterprise-grade Internet service, and won’t get provider-independent IPv6 address space because it’s too expensive. Even if they’d be willing to pay for enterprise-grade Internet access for every 3-person sales office in the middle of nowhere, do you really think that the global Internet would survive carrying provider-independent /48 prefixes for every single small office of every rich-enough organization out there?Ī similar one: small organization with two uplinks. Now for the trickier use case: small office of a large enterprise. It’s worth noting at this point that an Internet service that includes provider-independent address space advertised by BGP tends to be an order of magnitude more expensive than a residential service with the same speed… just because customers with such requirements are willing to pay more. The same approach works for an enterprise with multiple large sites. A large single-site organization with one or more Internet uplinks: get your own IPv6 address space and use BGP to advertise your prefix(es) to upstream ISPs.I describe the customer- and provider side of this setup in the Building Large IPv6 Networks webinar. Use provider-assigned IPv6 address (ideally delegated via DHCPv6 IA_PD) and put all your services into a cloud, or use dynamic DNS if you want to save $10/month. An organization with a single uplink to a single ISP: no problem.As long as the traffic from both uplinks doesn’t merge before being sent to upstream ISPs you don’t have a problem (the proof is left as an exercise for the reader) A consumer device with high-availability requirements: use two independent uplinks (WiFi + 5G).Let’s try to analyze where the problem might be. Enterprise shall select the ISP's based on the routing and preferences configured? Here’s another back-to-the-fundamentals question I received a while ago when discussing IPv6 multihoming challenges: I was wondering why enterprise can’t have dedicated block of IPv6 address and ISPs route the traffic to it.
